My sister is struggling with anxiety which is affecting her relationship. She reacts ridiculously over the top to minor things but most important is that she finds herself struggling in general. I am so happy that she reaches out to me when she’s feeling bad and I can usually perk her up but there are times when I am at a loss as to what to say. Is there anyone who has been where she is who can point me in the best direction as to how to approach helping her in the best way?
